RAM. Actually kernel code :( There no way to access ISA mem on
most Macs.

We can do _IO_, not ISA mem. Some cards require IOs accesses to
some VGA registers so we need the syscall to work. IOs are indeed
possible on all the UniNorth busses.

How ? If you get base for bus 0, you'll get the AGP which is what
you are looking for in this case.
